Entropy is a measure of disorder. One of the fundamental laws of physics indicates that it increases when the system consists of several different elements of equal or similar concentration. Therefore, the current model for developing new materials was based on the assumption that the alloy should have low entropy, i.e. have one leading element that is responsible for the most important properties of the material. It turns out, however, that high entropy in metal alloys combined with the distortion of the atomic lattice contributes to improving the functional properties of the material and not, as previously believed, to their deterioration. These surprising phenomena will be investigated by an international team of scientists led by prof. Łukasz Kurpaska as part of the project "Production of high-entropy alloys with high radiation resistance and increased mechanical properties at high temperature" financed by the National Science Center under the SONATA BIS program.

"Article, which title can be tranlated as 'Renewable energy sources or nuclear energy - what does Poland need?' was distinguished among many submitted works, which is a great proof of recognition from the jury and the journal's editorial staff. (...) The paper not only enriched the content of the Wiadomości Elektrotechniczne journal, but also contributed to expanding knowledge and inspiration for our readers," we read in the congratulatory letter

Understanding the structure of matter at the smallest scales is the greatest challenge faced by physicists today. Atoms consist of nuclei and electrons, nuclei of protons and neutrons, which in turn quarks bound together exist. In addition, the mass of all these particles is only a "side effect" of their interactions with each other or with the Higgs field, discovered experimentally over a decade ago. These interactions are modeled as the exchange of particles - gluons, photons and other so-called gauge bosons. And it is the properties of gluons that scientists from the National Center for Nuclear Research under the supervision of Dr. hab. Tolga Altinoluk will study in the project "Revealing the multidimensional structure of hadrons in the density saturation regime of high-energy gluonic collisions" financed by the National Science Center under the SONATA BIS programme.

Cancer diseases, which are the result of uncontrolled cell proliferation leading to the formation of tumors and disruption of organ functioning, significantly affect the quality of life and often lead to the death of the patient. Brain tumors are particularly difficult to treat due to their location in a vital organ, which limits surgical and radiotherapeutic options.

The National Centre for Nuclear Research and the MARIA Reactor represent a great potential that allows us to think with hope about the personnel and technological development of nuclear energy. It is also a unique research infrastructure on the map of Poland and the possibility of producing key radiopharmaceuticals for oncology therapies. These were the conclusions voiced during a visit by representatives of the United States and the Polish Atomic Energy Agency to the Świerk nuclear complex.
